Application February 15, 1957, Serial No. 640,541

1 Claim. (Cl. 144-296) The present invention relates to rack supports for holding doors on edge while jointing.

The present invention is a continuation-in-part from my co-pending application filed May 13, 1954, Serial No. 429,449 and later abandoned, entitled Rack or Support for Holding Doors While Jointing.

The primary object of the invention is to provide means for supporting a door on its edge to permit the door to be planed and to have jointing or mortising operations performed thereon for receiving hinges, locks, and other attachments.

A further object of the invention is to provide a support rack of the class described above which can be collapsed to occupy a minimum of space while not in use.

A still further object of the invention is to provide a support rack of the class described above which can be adjusted to accommodate doors of varying thicknesses.

Another object of the invention is to provide a support rack of the class described above which is inexpen" sive to manufacture, simple to use, and handy to carry when in collapsed position.

Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings, in which:

Figure 1 is a perspective view of the invention shown in door supporting position.

Figure 2 is an enlarged front elevation of the invention shown in collapsed position.

Figure 3 is an enlarged fragmentary top plan view of the invention with parts broken away for convenience of illustration.

Figure 4 is an enlarged fragmentary vertical crosssection taken along the line 4-4 of Figure 3, looking in the direction of the arrows.

Figure 5 is an enlarged fragmentary vertical crosssection taken along the line 55 of Figure 3, looking in the "direction of the arrows.

Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures, the reference numeral indicates generally a door holding support rack constructed in accordance with the invention.

The support rack 10 includes a generally rectangular base plate 11 having the corners 12 thereof bent slightly upwardly to permit the base plate 11 to be moved on a supporting surface without the comers 12 digging into the surface. The base plate 11 has a pair of notches 13 formed in the opposite side edges thereof for reasons to be assigned.

A bar 14 has the lower end thereof secured to one end ,of the base plate 11 by any suitable means such as welding or the like, with the bar 14 extending perpendicularly from the base plate 11. A U-shaped channel member 15 has the bight portion 16 thereof secured to the upper end of the bar 14 by means of welding or the like. A pair of spaced parallel arms 17 and 18 extend laterally from the bight portion 16 of the channel member 15 in upwardly spaced relation to the base plate 11.

A bushing 19 is welded or otherwise secured to the outer face of the bight 16 and to the outer faces of the arms 17 and 18 by welding 20. Each of the bushings 19 are provided with a bore 21 extending therethrough transversely thereof.

The arm 17 is provided with a bore 22 extending transversely therethrough and has a nut 23 axially aligned therewith and secured in overlying relation thereto by means of a plate 24 welded or otherwise secured to the nut 23 and to the arm 17. A threaded shaft 25 engages through the nut 23 and has a clamping plate 26 mounted on its inner end and a handle 27 secured to its outer end by means of which the shaft 25 is turned in the nut 23.

The bore 22 is of a size to permit the clamping plate 26 to be received completely therein when engaging the channel member 15 over a relatively wide door. A U-shaped channel leg 28 is engaged over each of the bushings 19 and pivotally secured thereto by means of pivot bolts 29.

The upper ends of each of the legs 28 are'beveled as at 30, as best seen in Figure 2, so as to engage the outer surfacesof the arms 17 and 18 and the outer surface of the bight 16 to limit the outward pivotal movement of the legs 28 from the base plate 11.

A pair of braces 31 are pivotally secure respectively to the legs 28 by means of pivot bolts 32 and are provided with angularly offset end portions 33 for engaging opposite sides of the bar 14 to lock the legs 28 in their outermost position. The inner ends of the braces 31 opposite the angular offset portions 33 are beveled as at 34 to engage respectively the legs 28 to prevent the braces 31 from pivoting below the horizontal.

The lower ends of each of the legs 28 are beveled as at 35 to permit the legs to engage a supporting surface in the same plane as the base plate 11.

In the use and operation of the invention, the legs 28 are each pivoted outwardly away from the bar 14 and locked in extended position by engaging the braces 31 against the bar 14. The base 11 is then placed on a supporting surface and a door, generally indicated at 36, is positioned on edge on the supporting surface with one end thereof engaged in the channel member 15 and with the lower portion of the same end of the door resting on the base plate 11. The handle 25 is turned bringing the clamping plate 26 into engagement with the door 36 clamping it against the arm 18 of the channel member 15, as illustrated in Figure 1. The carpenter then can plane, joint, and mortise the door for the hardware on the edge of the door while the door is firmly held in the support rack 10.

On the completion of the use of the support rack 10, it may be collapsed by raising the braces 31 out of contact with the bar 14 permitting the legs 28 carried by the arms 17 and 18 to engage in the notches 13 and the leg 28 carried by the bight 16 to engage against the edge of the base plate 11, as viewed in Figure 2. In this position, the support rack 10 can be transported, stored, or packed with other tools and will occupy a minimum of space.

Having thus described the preferred embodiment of the invention, it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the scope of the appended claims.

What is claimed is:

A door jointing folding support comprising a generally rectangular base plate having a flat undersurface and upturned corners, a bar fixed at its lower end to said base plate adjacent one end thereof and extending perpendicularly thereto, a channel member having the bight thereof secured to the upper end of said bar, said channel member having a pair of parallel arms extending toward the other end of said base plate and overlying said base plate, a bushing secured to each of said arms and said bight of said channel member and extending outwardly therefrom, a channel leg having the upper end thereof pivotally secured to each of said bushings, the upper ends of each of said legs being beveled to engage respectively against said arms and said bight with said legs spread apart in downwardly diverging relation with respect to said bar whereby to limit the extent of spreading of said legs, the lower ends of each of said legs being beveled at an angle to lie in the plane of the underside of said base with said legs in spread relation, a brace pivotally secured to each of said legs for engagement when in horizontal position with said bar for bracing the lower ends of said legs when spread, and a thumb screw extending through one of said arms and adapted to clamp a door against the other of said arms, said base having notches in the opposite side edges thereof to receive the lower end portions of said legs when said support is folded.
